Fresh on the heels of a possible skin implant that would allow us to get bronzed without actually going in the sun, scientists from King's College London are working on a pill that would replace sunscreen, and they say it could be available within five years. Coral produces natural sunscreen that prevents sun damage even though it grows in shallow water. Researchers hope to replicate this with a pill that would protect skin and eyes from UV rays and eliminate the need to slather yourself with a shot glass-sized portion of goo.
